Samurai Heavy Duty Curved Saw Replacement Blade, C-331-LHU

The C-331-LHU 13" (330mm) Samurai Heavy Duty, Non Tapered, Curved Hand Saw Replacement Blade for the C-330-LH Hand Saw was designed to take the punishment and abuse that even the most aggressive trimmer can dish out. The non-tapered set tooth blade offers excellent cutting edge durability through an impulse hardening process.



IMPULSE HARDENED TEETH

The blades are subjected to precision-controlled electronic impulses which heat and harden only the cutting edge of each individual tooth, making sure the razor-sharp cutting edge stays sharp cut after cut. This hardening process makes Samurai blades last three times longer than a conventional blade.



General Pruning Saw Information:

The two common blade profiles are "tapered" and "non-tapered." The tapered blade is thicker at the bottom where the teeth are and thinner at the top following edge. On a tapered blade, the teeth do not have a "set" (pushed left and right) therefore the blade following the teeth must be thinner to prevent drag in the saw kerf. A non-tapered blade has the same thickness from the top to the bottom. The teeth on a non-tapered blade have "set" to create a wider kerf at the teeth so the remaining blade can follow through the cut without drag. Typically a "nontapered" blade is more rigid than the tapered blade.



Tooth Style - The three-sided or tri-edge tooth has edges on both sides and across the top of the tooth. This style of tooth cuts much faster than the conventional two-sided tooth. The advantage of the conventional two-sided tooth is it is easier to sharpen.



Teeth per inches - refers to the number of saw teeth in one running inch of the saw blade. The smaller the number of teeth per inch the "coarser" the blades are. A blade with a higher number of teeth per inch is described as a fine-tooth blade.



Hardening - Impulse hardening is the most common method for hardening saw teeth. The process involves using electrical impulses to create a very hard layer on the sawtooth edge. The advantage of impulse hardening is a much longer tooth life. The disadvantage of an impulse-hardened tooth is it cannot be sharpened.



Mount - Many saw blades are punched with two different mounts (hole patterns) to allow one blade to serve as a pole saw blade and at the same time, a replacement blade for its respective hand saw. This "Dual" mount allows tree service professionals to order just one blade for both uses."
